Energy Breakthrough: China Creates Iron Battery, 80 Times Cheaper than Lithium and Lasting up to 16 Years 0 11

Chinese scientists have made a real breakthrough in the creation of iron-based batteries. A team from the Institute of Metal Research of the Chinese Academy of Sciences has significantly improved the technology of iron flow batteries, which are considered one of the most promising solutions for large-scale energy storage. They developed a unique electrolyte composition and modified the molecular structure of the iron compound, which brilliantly solved two major problems: preventing the degradation of the active material and minimizing its 'leakage' through the membrane.

The results of the tests were truly impressive. The prototype of this battery successfully endured an incredible 6000 charge and discharge cycles, equivalent to more than 16 years of uninterrupted daily use, while losing not a drop of its initial capacity. Furthermore, the developers report minimal leakage and high operational efficiency, reaching 78.5%.

It is important to note that no harmful byproducts or sediment formed inside the battery, and its structure remained absolutely stable throughout the testing period. This achievement gains particular significance in the context of the constantly growing demand for reliable energy storage systems for modern power grids. Considering that iron is tens of times cheaper than lithium, such technologies pave the way for creating much more affordable solutions for effective storage of solar and wind energy at large industrial sites.
